Estimating the sensitivity of cervical cytology: errors of interpretation and test limitations.

The objective of this study was to estimate: (i) the sensitivity of cytologists in recognizing abnormal smears; (ii) the sensitivity of cervical cytology as a method of detecting abnormal smears among those obtained in the presence of cervical intraepithelial neoplasia (CIN). Study subjects were 61 women with a histologically confirmed CIN identified through colpohistological and cytologic screening. For objective (i) new smears were taken from study subjects just before treatment, mixed with routine preparations, interpreted by unaware cytologists and then blindly reviewed by a group of three expert supervisors, who reached a consensus diagnosis.

[Role of viral infections in the genesis of dysplasias of the uterine cervix].

A study of 80 cases of dysplasia of the uterine cervix showed the coexistence of HPV infections in 52 cases. This association (65%) shows the important role played by the human papilloma virus in the genesis of cancer of the cervix.

Fine-needle aspiration of breast lesions: role and accuracy in a review of 7,495 cases.

In the past 10 years, 7,495 cytological breast fine-needle aspirations (FNAs) were performed (4,756 FNAs of solid nodes and 2,739 of cystic nodes). Of these, 2,099 cases underwent surgery; 650 (31%) had histologically proven carcinoma. Sensitivity was 83.
